Problems solved by technology

Generally, AGV robots only use RFID tags to realize path navigation, such as the utility model patent CN 203405960 U, the non-directionality of RFID tags makes it impossible for the path navigation system to obtain the robot offset angle and the robot offset RFID center point distance; and the AGV robot only Use two-dimensional code labels to realize path navigation, such as the invention patent application CN 103268119 A, then two-dimensional code labels get wrong robot position information when the AGV is running at high speed

Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] Such as figure 1 Shown is a structural block diagram of an AGV robot path navigation system, which includes a two-dimensional code label, an RFID label, a two-dimensional code image acquisition system, an RFID reading system, a servo motor system, a communication system and an embedded industrial control board; The two-dimensional code image acquisition system and the RFID reading system respectively read the two-dimensional code label and the RFID label information and upload them to the embedded industrial control board through the communication system, and the embedded industrial control board is passed as follows: Figure 4 The shown method outputs forward or differential speed adjustment or parking adjustment commands to the servo motor system after judgment processing, so that the robot can confirm its own posture in the walking environment and c...

Abstract

The invention provides an AGV robot path navigation system, and belongs to the technical field of robots. The AGV robot path navigation system comprises a two-dimensional code tag, an RFID tag, a two-dimensional code image acquisition system, an RFID reading system, a servo motor system, a communication system and an embedded industrial control board. The two-dimensional code image acquisition system and the RFID reading system read information of the two-dimensional code tag and the RFID tag respectively, the information is uploaded to the embedded industrial control board through the communication system, the embedded industrial control board outputs forward or differential adjustment or stop adjustment commands to the servo motor system after judgment processing, and a robot confirms the pose of the robot in a walking environment and corrects the walking direction. The system is simple and easy to implement, the three-dimensional code tag and the RFID tag are overlapped in the duplex system, the pose loss probability of the robot is greatly decreased, the system can automatically confirm the position of the robot in the walking process and automatically correct the robot walking direction, and high automatic transport efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to an AGV robot path navigation system. Background technique [0002] Unmanned guided vehicle (AGV robot for short) refers to a transport vehicle equipped with automatic guidance devices such as electromagnetic or optical, capable of driving along a prescribed path, with safety protection and various transfer functions. For AGV robots with autonomous path planning functions, it is very important to confirm their position on the map, and to correct the direction of the robot in real time, which is conducive to improving the efficiency of the transportation industry. Generally, AGV robots only use RFID tags to realize path navigation, such as the utility model patent CN 203405960 U, the non-directionality of RFID tags makes it impossible for the path navigation system to obtain the robot offset angle and the robot offset RFID center point distance; and the AGV robot only Using two...
